Airmen from the 823d Base Defense Squadron practice tactical combat casualty care as part of the Mission Readiness Exercise (MRX) scenario at Camp Guernsey, Wyo., March 26, 2019. Under the supervision of a medic, the Airmen inserted an IV into the simulated victim’s arm. The MRX scenario put small, isolated teams of defenders in multiple stressful scenarios to practice decision making in an adaptive basing situation. (U.S. Air Force photo by 1st Lt. Faith Brodkorb)
